T115/70D16 90M is an example of a tire size and load index rating.
Here is an explanation of the various components of that tire s ize and
load index rating. Note that the tire size and load index ratin g may be
different from the example.
● T
Indicates a tire that may be installed on cars, SUVs, minivans and
light trucks as desig nated by the Tire and R im Association (T&RA).
● 11 5
“115” is the nominal width of th e tire in millimeters. This three-digit
number gives the width in millimet ers of the tire from sidewall edge
to sidewall edge. In general, the larger the number, the wider the
tire.
● 70
“70” is the aspect ratio. This two-digit number indicates the t ire’s
ratio of height to width.
● D
“D” is the tire construction symbol. D indicates “diagonal ply con-
struction”.
● 16
“16” is the wheel rim diameter in inches.

7-7. Tire Information (U.S.A.)
Location of the Tire Label (Placard)
You will find the tire label containing tire inflation pressure by tire size
and other important i nformation on the driver’s side B-pillar o r on the
edge of the driver’s door frame.
SAMPLE
On the tire label you will find t he recommended tire inflation pressure
in both kPa and psi for the tire s installed as original equipment on the
vehicle. It is very important that the inflation pressure of th e tires on
your vehicle is maintained at t he recommended pressure. You sho uld
check the tire pressure regularly to insure that the proper inf lation
pressure is maintained. Refer to Tires on P. 553.
Tire pressures listed on the vehicle placard or tire informatio n label indi-
cate the recommended cold tire inflation pressure, measured whe n the
tires are cold, after the vehicle has been parked for at least 3 hours. As
you drive, the temperature in the tire warms up, increasing the tire pres-
sure.

7-7. Tire Information (U.S.A.)
●Tire Placard: A label indicating the OE tire sizes, recommended
inflation pressure, and the maxi mum weight the vehicle can carry.
● Tire Identification Number (TIN): A number on the sidewall of e ach
tire providing information about the tire brand and manufacturi ng
plant, tire size, and date of manufacture.
● Inflation Pressure: A measure of the amount of air in a tire.
● kPa: Kilopascal, the metri c unit for air pressure.
● psi: Pounds per square inch, the English unit for air pressure.
● B-pillar: The structural member at the si de of the vehicle behind the
front door.
● Original Equipment (OE): Des cribes components originally
equipped on the vehicle.
● Vehicle Load Limit: The maximum value of the combination weight
of occupants and cargo.
● Bead Area of the Tire: Area of the tire ne xt to the rim.
● Sidewall Area of the Tire: Area between the bead area and the
tread.
● Tread Area of the Tire: Area on the perimeter of the tire that con-
tacts the road when it’s mounted on the vehicle.
● Seating capacity means the total allowable number of vehicle oc cu-
pants. Seating capacity is described on the tire label.
● Production options weight is the combination weight of installe d
regular production options weighin g over 2.3 kilograms in excess of
the standard items whic h they replace, and not previously consid-
ered in the curb weight or accessory weight, including heavy du ty
brakes, ride levelers, roof rac k, heavy duty battery, and speci al trim.
● Rim is the metal support (wheel) for a tire or a tire and tube assem-
bly upon which the tire beads are seated.

7-7. Tire Information (U.S.A.)
GCWR (Gross Combination Weight Rating) is the maximum allowable
weight of the vehicle - including all cargo and passengers - that the
vehicle can handle without risk ing damage. The GCW must never
exceed the GCWR.
WARNING
■Do not tow a trailer with this vehicle
Towing a trailer with this vehicle is dangerous because it has not been
designed to tow a trailer and do ing so will affect the drive system which
could result in vehicle damage.
■Overloaded Vehicle
Overloading a vehicle is dangerous. The results of overloading can
have serious consequences in terms of passenger safety. Too muc h
weight on a vehicle’s suspensi on system can cause spring or sho ck
absorber failure, brake failure, handling or steering problems, irregular
tire wear, tire failu re or other damage.
Overloading makes a vehicle harder to drive and control. It als o
increases the distance required for stopping. In cases of serio us over-
loading, brakes can fail completely, particularly on steep grad es. The
load a tire will carry safely is a combination of the size of t he tire, its load
range, and corresponding inflation pressure.
Never overload the vehicle and always observe the vehicle’s wei ght rat-
ings from the vehicle’s Safety C ertification and Tire and Load Informa-
tion labels.
■Never Exceed Axle Weight Rating Limits
Exceeding the Safety Certification Label axle weight rating lim its is dan-
gerous and could result in death or serious injury as a result of substan-
dard vehicle handling, performance, engine, transmission and/or
structural damage, serious damage to the vehicle, or loss of control.
Always keep the vehicle within the axle weight rating limits.
■Never Exceed GVWR or GAWR Specifications
Exceeding the GVWR or the GAWR specified on the certification l abel is
dangerous. Exceeding any vehicle rating limitation could result in a seri-
ous accident, injury, or damage to the vehicle.
Do not use replacement tires with lower load carrying capacities than
the originals because they may lower the vehicle’s GVWR and GAW R
limitations. Replacement tires with a higher limit than the ori ginals do
not increase the GVWR and GAWR limitations. Never exceed the
GVWR or the GAWR specified on the certification label.
